The dual thermometer module is a compact and versatile solution for simultaneously monitoring temperature at two distinct points, displaying the values in real time on a 3-digit 0.28-inch LED display. It can be used in automotive, industrial, or DIY applications thanks to its wide power supply range of 4 to 28 VDC, making it compatible with various voltage sources available in these environments.
The module is equipped with two sealed (waterproof) NTC sensors, each with an approximately 1 m cable, which can be placed in air, liquids, or mounted on surfaces, with hole mounting. This flexibility allows simultaneous measurement in scenarios such as indoor/outdoor, water inlet/outlet, or radiator/ambient. The measurement range is -20 ~ 100°C, sufficient for most common thermal applications. The LED display shows values in degrees Celsius, presenting both channels simultaneously in a clear format, readable even in low-light conditions, with different colors. The module’s compact dimensions (45 x 26 mm) make it easy to integrate into an enclosure or control panel.
The module requires no programming and works plug-and-play, making it accessible to both beginners and advanced users.
Specifications:
Power supply: 4 - 28 VDC
Display: 3-digit LED, 0.28 inch
Sensor type: sealed NTC (waterproof)
Number of sensors: 2
Temperature range: -20 ~ 100°C
Sensor cable length: ~1 m
Module dimensions: 45 x 26 mm
Usage:
Connect the positive wire of the power supply (4-28 VDC) to the VCC terminal and the negative wire to the GND terminal.
Connect the first NTC sensor to input S1 and the second sensor to input S2.
Turn on the power. The module activates automatically and starts displaying the temperature for both channels.
Position the sensors at the desired measurement points: in air, immersed in liquids, or attached to metal surfaces or pipes.
Read the temperature values directly from the LED display in degrees Celsius.
Mount the module in an enclosure or on a panel, using the 45 x 26 mm dimensions as a reference for cutout or installation.
Warning. Do not exceed the maximum voltage of 28 VDC to avoid damaging the module. For use in liquids, make sure the sensor’s sealed area is completely submerged, while the connectors and cable remain outside the liquid and dry.
